source code如下:

import java.io.FileNotFoundException; import java.io.IOException; import org.apache.commons.codec.binary.Base64; import org.apache.http.HttpEntity; import org.apache.http.HttpResponse; import org.apache.http.client.ClientProtocolException; import org.apache.http.client.HttpClient; import org.apache.http.client.methods.HttpPost; import org.apache.http.entity.mime.HttpMultipartMode; import org.apache.http.entity.mime.MultipartEntityBuilder; import org.apache.http.impl.client.DefaultHttpClient; import org.apache.http.util.EntityUtils;@SuppressWarnings("deprecation") public class MyHTTPPost {final private static String POST_PREFIX = <replace with your own application server url>;private static String getRequestURL(String str){String url = POST_PREFIX + str;url = url + "&sid=" + Math.random();return url;}private static void sendHTTPPostRequest(String str) throws FileNotFoundException{ HttpClient httpclient = new DefaultHttpClient();String raw = "WANGJER:Saptest1"; String encoded = Base64.encodeBase64String(raw.getBytes());HttpPost httppost = new HttpPost(getRequestURL(str));MultipartEntityBuilder builder = MultipartEntityBuilder.create(); builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);builder.addTextBody("firstName", "Jerry");builder.addTextBody("lastName", "Wang");try {httppost.addHeader("Content-Type","multipart/form-data; boundary=assdsfdffafasf");httppost.addHeader("User-Agent","Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)");httppost.addHeader("Authorization", "Basic " + encoded); HttpResponse httpresponse = httpclient.execute(httppost);HttpEntity resEntity = httpresponse.getEntity();String response = EntityUtils.toString(resEntity);System.out.println(response);}catch (IOException e){System.out.println(e.getLocalizedMessage());e.printStackTrace();System.out.println("error!");}}public static void main(String[] args) throws ClientProtocolException, IOException { sendHTTPPostRequest("a");} }

運行結果:
application server會解析出Java program傳入的http 請求中的"a", 然后從DB table scarr 中查找對應的記錄，返回給Java side:
